Call of Duty®: World at War completely changes the rules of engagement by redefining WWII gaming and thrusting players into the final tension-filled, unforgiving battles against a new ferocious enemy in the most dangerous and suspenseful action ever seen in WWII.

Call of Duty World At War, a return to classic Call of Duty... Or is it?

Campaign: The campaign immerses the player in an American soldier fighting in the grim Pacific Theater and a Russian soldier fighting in the battle to take revenge on Germany for invading their country. I have to say, most of the American campaign was very forgettable. Some of the Russian campaign was, too, but it was more interesting, in my opinion. They both did capture the grim reality of World War 2, though. I give it an 8/10.
Gameplay: For the most part, it was great. The AI was sort of intelligent, but still wasn't great like when my fellow soldiers constantly run into the line of fire. Multiplayer is alright, but it's not the best. It is fun for when you are bored. I give the gameplay a 7/10.
Multiplayer: World at War brings the Call of Duty multiplayer back to World War 2... and I don't like it. For one, it doesn't have that same faced paced multiplayer that you can play to earn weapons and perks. I just didn't enjoy this as much and the servers are just ridiculous. I've seen servers saying you can't use your perks and such. I earned them, but I can't use them because it may give me an advantage? The Co-op redeems that mess, thankfully. All in all, I give the multiplayer a 8/10.
Nazi Zombies: World at War brought in something new and wildly popular that spread like a wildfire, Nazi Zombies. A fun and difficult survival game. It just isn't fun to play Solo after a while, though. Not to mention how few levels there are. I recommend playing this with at least one other person. I give it a 9/10.
Graphics: They are beautiful. I've seen better, but they are incredible. The gore adds to the atmosphere and the level of detail is exquisite. I give them a 10/10.

Summary:
For those of us who joined the series in the beginning, it's nostalgia in a box. For the rest of you, it's a fun and entertaining game I would recommend to any FPS fan. I give it an 8.4/10
